ELECTRICAL FITTING CoNNEoTIoN.

Specification of Letters Patent.

Patented May 17, 1921.

Application filed October 25, 1919. Serial No. 333,386.

carried by a canopy and for this purpose the canopy is provided withspecial members to afford pivotal supporting means for the terminalmember.

The main object and feature of the present invention is to admit of theuse of standard fixtures, without necessity of alteration in connectionwith the invention of said Letters Patent. To this end, the bushing ofthe canopy is employed, the leads being passed through it as a supportfor the mounting of the pivotally supported terminal member.

Other features of the invention will appear as the specificationproceeds.

In the accompanying drawings the inven tion is shown in a concrete andpreferred form, in which- Figure 1 is a sectional view, on line 1-1 ofFig. 2, through a canopy and electrical fitting connection embodying myinvention.

Fig. 2 is a view in elevation of the parts shown in Fig. 1, looking inthe direction of arrow of Fig. 1, the canopy being broken away and itsoutline indicated in dotted lines.

Fig. 3 is a detail View, partly broken away, of the mounting for theterminal member with the latter indicated in dotted lines.

The mounting consists of two jaws 1 that are in superposed relation andconnected by means of a pivot 2 so that they will open or close in amanner similar to that of a pair of scissors. Each jaw is provided withan angularly extending lug 3 having an aperture 4. It will be seen that,when the jaws are swung into a iven position, apertures 4c, whichconstitute earings for the terminal member 5, will be in alinement andthe terminal 6 will enter said aperture. 7 indicates an opening in eachjaw and these openings are brought into register when the bearings forthe pivotally supported terminal member are in alinement. 8 is a canopyof standard construction having a bushing or hollow support 9. Thisbushing is introduced through openings 7, there 1 by preventing jaws 1from swinging on pivot 2. 10 is a lock nut for holding the mount on thehollow support. 11 indicates flexible connections, from the terminalmember, that extend through bushing 9 of the canopy to the branches ofan illuminating appliance as for instance a wall-bracket.

An advantage of the construction shown resides in the fact that when themounting is removed from the support, the pivotally supported terminalmember may be quickly removed from the mounting by opening of the jaws.I have also found that the scissors feature of the device can be omittedand a one part device with arms forced into the shell, but theadvantages are obviously with the scissors construction.

I claim:

1. An electrical fitting comprising: a mounting for a terminal memberconsisting of two superposed and pivotally connected jaws, an angularlyextending lug carried by each jaw, said lu 5 having bearings that are inalinement wit each other when the jaws are swung into a given position,and a terminal member pivotally and removably supported in saidbearings.

2. An electrical fitting comprising: a mounting for a terminal memberconsisting of two superposed and pivotally connected jaws, an angularlyextending lug carried by each jaw, said lugs having bearings that are inalinement with each other when the jaws are swun into a iven osition anda ter- I minal member pivotally and removably supported in saidbearings, and means for preventing the jaws from swinging on theirpivot.

3. An electrical fitting comprising: a

mounting fora terminal member consisting of two superposed and pivotallyconnected jaws, an angularly extending lug carried by 7 each jaw, saidlugs having bearings that are in alinement with each other when the jawsare swung into a given position, and said jaws having openings that arein register when the bearings are brought into alinement, a fixturesupport extending through the registered openings, means for securingthe jaws to the support, and a terminal member pivotally supported insaid bearin s.
